How many moles of hydrogen are needed to produce 13.78 mol of ethane?
Answers
This is an incomplete question, here is a complete question.
The following balanced equation shows the formation of ethane (C₂H₆).
How many moles of hydrogen are needed to produce 13.78 mol of ethane?
1) 3.445 mol
2) 6.890 mol
3) 27.56 mol
4) 55.12 mol
Answer : The number of moles of hydrogen needed are, (3) 27.56 mol
Explanation : Given,
Moles of ethane = 13.78 mol
The given balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 1 mole of ethane produced from 2 moles of hydrogen
So, 13.78 mole of ethane produced from moles of hydrogen
Thus, the number of moles of hydrogen needed are, 27.56 mol

Since Washington was a qualified and professional leader during the French and Indian Wars, they believed that he would make a terrific one for the Continental Army as well. Considering that he was given authority over such a weak and poor army, he somehow handled to force the British out of Boston in 1776 and soon closed the war by having victory at Yorktown in 1781.

Elements and compounds are types of mixtures.
Pure substances are made up of mixtures combined in specific ratios.
Mixtures are classified based on the distribution of particles in them.
Answers
Answer: Option (d) is the correct answer.
Explanation:
When two or more different substances are mixed together then it results in the formation of a mixture.
Mixture are of two types, that is, homogeneous mixture and heterogeneous mixture.
In homogeneous mixture, the constituent particles are distributed evenly throughout the mixture.
Whereas in heterogeneous mixture, the constituent particles are non-uniformly distributed.
Thus, we can conclude that mixtures are classified based on the distribution of particles in them.

Answer: In order to a solute to dissolve in a solvent, both the attraction forces that bind the units of solute together and the intermolecular forces that bind the molecules of solvent together must be weaker than the attraction forces between the particles of solute and the molecules of solvent.
Explanation:
The solute particles in are binded together in virtue of attractive forces (the nature and strength of these forces depends on the particular solute).
The same happens with the solvent molecules: they are binded by attractive forces (similarly, the nature and strength of these forces depend on the particular solvent).
To get dissolved (form solution) the particles of solute must be separated and mixed with the solvent particles in a process called solvatation.
The solute particles must surrounded by the solvent particles.
When the forces of attraction between the solute particles and the solvent are stronger than the forces of attraction that bind the solute particles, the solute particles move away from the solid solute and are integrated into the solution.
